PX Image Optimizer – Free Joomla Image Compression & WebP
Compress and resize images on upload, serve WebP automatically and optimize the images you already have. Originals are kept for one-click restore. Free.
Compress and resize Joomla images on upload
Images you upload in the Media Manager are scaled down to a maximum size, cleaned of camera and GPS data and recompressed before they are saved. You keep working as before.
- Max width and height (2560 px by default)
- EXIF / GPS removed, orientation fixed
- Balanced or lossless quality
Optimize the images already on your site
Pick a folder and PX Image Optimizer works through it in batches, right in the browser. Images that are already done are skipped, so you can run it again whenever you like.
- Any folder under images, files or media
- Batches of up to 50 files
- Optimized, skipped and failed counts
Keep every original, restore with one click
The original of every changed image is kept outside your images folder. The Images list shows the size before and after, and Restore puts the original back.
- Before, after and saved per image
- One-click restore
- Savings totals on the dashboard
Serve WebP on your Joomla pages automatically
A WebP copy is saved next to each JPEG and PNG, and local images on your pages are wrapped in a picture tag, so browsers that support WebP load the smaller file. Your articles stay unchanged.
- WebP next to each JPEG and PNG
- Picture tags added when the page is sent
- Imagick or GD, checked for you
